Walker 350-64067 Oxygen Sensor - Upstream, Upstream Left or Upstream Right

Walker 350-64067 Oxygen Sensor Overview

Walker Products 350-64067 is a heated oxygen sensor built as a specific-fit OE-style replacement for select Nissan and INFINITI applications. It is engineered for upstream placement and provides the ECU with the feedback needed for accurate fuel control and emissions monitoring.

For drivers diagnosing a check engine light, poor fuel economy, or elevated exhaust emissions, this Walker Products Aftermarket sensor is designed around the application-specific fitment and connector layout required for the vehicle.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for direct application matching
• 4-wire configuration with male connector
• Threaded mounting type with 18.0 mm thread diameter
• Wiring harness length: 15.87 in.
• Overall length: 19.41 in.
• Radiused polygon connector shape for vehicle-specific connection
• Fits upstream sensor locations on select Nissan Cube, Nissan Sentra, and INFINITI FX50 applications

Detailed Description

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered as OE replacement parts for a wide range of vehicles. Part number 350-64067 is built for specific fitment positions and is intended to deliver the diagnostic feedback the ECU expects from the upstream oxygen sensor circuit. This makes it a practical choice for 2011-2014 Nissan Cube upstream applications, 2009-2012 Nissan Sentra upstream applications, and 2009-2012 INFINITI FX50 upstream left or upstream right applications.

The Walker Products 350-64067 oxygen sensor uses a heated, threaded design with a 4-wire harness and male connector. If the original sensor has failed or the wiring and connector show damage, the vehicle may store fault codes and exhibit drivability or emissions concerns. This part cross-references no additional part numbers provided for this application.

What It Helps Address

• Check engine light related to upstream oxygen sensor faults
• Poor fuel economy caused by incorrect air-fuel feedback
• Rough running or inconsistent engine performance
• Elevated exhaust emissions from a failing sensor
• Stored ECU fault codes tied to sensor circuit issues

Installation Notes and Tips

Install this sensor only in the listed upstream positions for the confirmed vehicle applications. Before replacement, inspect the sensor wiring harness and connector for heat damage, corrosion, or broken terminals, since those issues can shorten sensor life and affect signal quality. Verify thread size, connector shape, and harness length against the original part before installation.
